Title: Conversion circuit selectively reducing higher harmonic component of digital-synthesizer excitation signal

Title: Manufacture of circular fluorescent lamp with flat section
Inventor: TAIRAKU SEIICHI
IPC: H01J9/24
Filed: 1987-09-04
Abstract: PURPOSE:To manufacture circular fluorescent lamps with flat section effectively by heating uniformly with specific temp. immediately before takeup of the glass tube temp. CONSTITUTION:The glass tube temp. is heated uniformly at 700-900 deg.C immediately before taking-up. Too low temp. of the glass tube 1 does not bring about favorable softened condition, and it is hard to be drawn into a groove, so that it is not laid alongside the drum groove 2'. Thus a proper figure is not obtained. Too high temp. of the glass tube 1, on the other hand, gives the glass at the top a small wall thickness owing to the own weight of the glass tube, and because it is taken up in this condition to cause drop of the glass strength and because the shape is easily collapsed due to influence of the inner pressure, it is hard to finish into a flat section with strength retained. Thus it is necessary to control the glass tube temp. to the abovementioned temp.

Title: Amplification factor monitoring circuit
Inventor: ISHIKAWA AKIRA
IPC: H03G3/30
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To generate an amplification factor monitoring signal for accurately monitoring the amplification factor of an amplifier. SOLUTION: A dummy AGC amplifier 3 is thermally connected to an AGC amplifier 1 and has the same constitution as that of the amplifier 1 and its amplification factor is controlled by an amplification factor control signal VC applied from an automatic amplification factor adjustment control circuit 2. When the amplifier 1 is driven at an amplification factor GA according to a control signal VC, the amplifier 3 is also driven at the amplifi-cation factor GA according to the control signal VC. Since a reference signal VREF inputted to the amplifier 3 is fixed, the amplification factor GA is proportional to the output VG of the amplifier 3. An output VG is independent of temperature and power supply voltage.
